The ASC Engineered Solutions 308009604 is a Class 125 black cast iron reducing flange used in low-pressure piping systems to connect pipes of differing diameters or to transition from pipe to flat mating surfaces. With a 3-inch bore and a 10-inch outer diameter, this flange provides a reliable mechanical connection point in drainage, industrial, and general plumbing applications. The black coating provides basic corrosion resistance for above-ground service. At 17 pounds, the flange is built to the dimensional and pressure standards expected of Class 125 cast iron fittings. Installation is performed by licensed plumbers and pipefitters working on commercial or industrial systems.
This reducing flange is suited for commercial and industrial piping installations where a 3-inch pipe must interface with a larger bolt-circle or mating flange assembly. The 10-inch outer diameter accommodates standard Class 125 bolt patterns, making it appropriate for pump connections, valve flanges, and equipment tie-ins in water, wastewater, and general-service piping. Domestic manufacture supports traceability requirements common in municipal and institutional projects.
Designed as an OEM-style replacement and standard-fit component for Class 125 cast iron flanged piping systems in commercial and industrial plumbing applications.
Installation is performed by a licensed plumber or pipefitter. Isolate and depressurize the piping system completely before removing any existing flanges or beginning assembly. Use appropriate gasket material rated for the service fluid between mating flange faces, and torque flange bolts in a cross-pattern sequence per applicable codes such as IPC or ASME B31. Inspect the flange face and bore for damage before installation.
